Dyeing auxiliaries and their use in dyeing synthetic fibers

DE-PS 20 33 894 means and methods for dyeing or Printing of textile fibers, threads or materials made therefrom made of linear aromatic polyesters with these agents is known, in which with disperse dyes in the presence of such dye on carriers (carrier) is dyed, which is at least 30 percent by weight Contain alkylbenzenes; the preparations mentioned there can also contain emulsifiers or dispersants in order to distribute them in to improve the dye liquors. As such, there are already polyethylene oxide adducts on castor oil, but all the preparations mentioned there always contain an anionic component as one component Disperser.

It has now been found that polyester fibers, threads or made from them can be produced It is particularly advantageous to dye or print textiles if the dye carrier (carrier) used is a mixture of the above aromatic compounds, and only certain non-ionic dispersant mixtures and higher-boiling aliphatic * hydrocarbons used.

The present invention therefore relates to dyeing aid preparations containing (a) 70-87.5% of a mixture consisting of more than 30% by weight of alkylbenzenes in which the benzene nucleus has two or more methyl radicals or at least one ethyl, propyl or butyl radical as a substituent and whose boiling range 160-280 ⁰ C, (b) 10-20% of a polyglycolized with 30-50 mols of ethylene oxide castor oil, (c) 0.5-5% of a fatty acid (5-8) polyglykolesters and (d) 2 -5% paraffin oil, and these preparations do not contain an anionic dispersant.

The present invention also relates to the use of aforementioned means for dyeing textiles made of polyester, cellulose

acetate or their mixtures with other fibers, especially wool, with Dispersion dyes or their mixtures with other dyes and dyeing processes with these agents.

The aromatic component (a) of the mixture is obtained, for example, as a distillation residue in the industrial production of ortho-, meta- or para-xylene or other alkylbenzenes, in industrial cracking and hydrogenation processes, among other things. It usually contains more than 50 percent by weight, preferably at least 70 percent by weight, of the aforementioned alkylbenzenes and, in addition, up to 30% of such distillation residues as biphenyl, naphthalene, anthracene, phenanthrene, fluorene and their derivatives. The boiling range of these mixtures is, as stated, at atmospheric Bedinge busbars 160-280 ⁰ C. If the last-mentioned high molecular weight compounds in the distillates are not present, the boiling range of the mixture is from 180 to 215 ° C (especially up to 190 ⁰ C).

Other mixtures of the above-mentioned type are for example those with 80% Diäthylbenzolen as a main component and about 20% butyl, triethyl- and Tetraäthylbenzolen (boiling range 150-180 ⁰ C), those with 90 parts of isomeric trimethylbenzenes and about 10 parts of higher alkylbenzenes having a boiling range of 170-215 ⁰ C. The component (a) is preferably present at 78 to 84% in the inventive mixture.

According to the invention, the mixtures contain in addition to the aromatic ones mentioned Hydrocarbons (a) as dispersants a mixture of two ι of nonionic types, the former of which (b) is a castor oil poly (30-35) glycol ether is, which is present in amounts of 10-20%, preferably 10-15% in the mixture, and the second (c) a fatty acid (C- ,, - *) before especially an oleic acid-poly (5-8) -glycol ester, which is 1-5% in a mixture, preferably about 2% is present. Paraffin oil, the fourth component (d), is 2-5%, preferably about 4-5%, present in the mixture.

- 5 - Case 150-4419

When using the mixture according to the invention, when dyeing with Disperse dyes in general on customary other carriers such as diphenyloxide, methyl benzoate or halogen-containing compounds aromatic character can be dispensed with. The mixtures according to the invention have an extremely balanced coloring Effect.

The preparations according to the invention are further distinguished by a marked lack of foam and often even have a defoaming effect. In addition to a very good carrier effect, which is particularly effective in the case of dyes of strong color strength (depth of color!), The auxiliaries according to the invention have a leveling effect. They also promote migration outstandingly, which proves to be advantageous in the case of substrate-related streakiness, especially with PES textiles that are stretched differently. This has a particularly advantageous effect at temperatures above 100 ^° C. (up to 130 ^{° C.).} It should also be emphasized that the dispersion stability is not adversely affected by disperse dyes (especially with PES rapid dyeing processes).

The dyeing or printing is carried out with the auxiliaries according to the invention in a familiar way. The preparations are used in amounts between about 2 to 35%, based on the weight of the material to be treated, added.

In the following examples, parts mean parts by weight and Percentages by weight. The temperatures are given in degrees Celsius.
